Relationships between increased chronological age and decreased white matter integrity (fractional anisotropy, FA) in the splenium (upper left) and genu (upper right) of the corpus callosum, fornix cres (lower left), and external capsule (lower right) are presented across the full sample (black line; bolded, FDR-adjusted p < 0.012). These relationships did not differ between cognitively normal (black circles, dashed line) and cognitively impaired-not demented (CIND; gray circles, dotted line) subgroups. The effect of age on splenium FA was significantly stronger than the effect of age on genu FA.
